Candidates should approach the interdisciplinary nature of the UPSC syllabus by integrating knowledge across various subjects. Understanding the connections between politics, economics, and geography allows for a holistic view of national and international issues. Aspirants should prioritize thematic learning, which connects different subjects through common frameworks or themes. Engaging in discussions that link various fields can deepen understanding and enhance retention. This approach not only prepares candidates for questions that require multidisciplinary perspectives but also equips them with analytical skills necessary for civil service roles.
